As technology continues to evolve, sound signaling remains a vital element in electronic systems—whether for 

alerts, status indicators, or functional feedback. At RHT, we provide reliable, efficient, and compact acoustic 

solutions through our Externally Driven Magnetic Buzzers.

What Are Externally Driven Magnetic Buzzers?

Externally driven magnetic buzzers require an external driving signal (typically square wave), giving designers 

more control over frequency, tone, and volume. These buzzers are known for their energy efficiency and stable 

performance in diverse environments.

Our RHT+Externally Driven Magnetic Buzzers are crafted for high reliability, low power consumption, and 

consistent acoustic output—ideal for demanding electronic applications.
